Frequently Asked Questions
Where does the Cummins 4945701 bellhousing adapter cam seal install?
This rectangular-ring seal installs between the rear of the engine block and the bellhousing adapter plate. It specifically seals the rear camshaft port/bore to prevent oil from leaking out around the adapter.
Which trucks does this Cummins 4945701 seal fit?
It is used on 2003–2007 Dodge Ram 2500/3500 5.9L Cummins and 2007.5–2024 Ram 2500/3500/4500/5500 6.7L Cummins applications that use the rectangular-ring style bellhousing adapter cam seal. Always verify your VIN and engine family before ordering.
Should I replace this seal every time I pull the transmission or bellhousing adapter?
Yes. Any time the bellhousing adapter plate is removed from the block, this rectangular-ring seal should be replaced. Re-using a compressed seal is a common cause of new leaks after clutch, flywheel, or transmission work.

What other Cummins seals should I replace at the same time?
Many customers replace this bellhousing adapter cam seal along with other rectangular-ring and gasket components when the drivetrain is apart. Consider pairing it with the CP3 gear housing rectangular-ring seal and oil pickup tube gasket:
